摘要: Abstract : Turbulent flow over sinusoidal pipes with amplitude-wave-length ratios of 1/45 and 1/90 was studied. The scope the investigation includes following: (1) measurements turbulent characteristics, total head pressure distributions, mean velocity profile, turbulence intensities distribution, Reynolds stress variation boundary shear stress; (2) analytical result predicting profile; (3) approach finding an empirical formula for local friction factor.
